Application flledseptember 29, i910. a Serial No. 122,922,

To all whom it may concern: Be it known that I, ABRAM SWARZMAN,

; a citizen'of the United States, and a resident new and useful Improvements in T05 -.t'-

of Sioux City, in the county'of 'Woodbury and State of. Iowa, have invented certain Ventilators, of which" the following is a specification.

The present invention relates 'to means for ventilating toilets.

The invention has for its primary object I the production of an improved sanitary ,ventilating device adapted to convey the foul air and gases from water-closet bowls.

Another object of the inventlon' is the production of an improved toilet-ventilator simple and inexpensive in production, thor- 1 oughly eflicient in operation and adapted to be readily applied to water-closets now in use. t

Still another object of the invention is the production of a ventilator embodying an improved toilet-ventilating seat adapted to supplant the. seats now in common use on.

water-closets.

With these and other objects in view, the invention, consisting in the construction,

combination and novel arrangement of parts, will be fully understood from the folowing description, reference being had to l the accompanying drawings,-zwhichform a part of this application and in which like characters of reference indicate correspond ing parts throughout the several views, of

wh1ch,-

Figure 1 is a side elevation of the preferred embodiment of the invention, parts being cutaway and shown in section;

,Fig. 2 is a plan of the same, the valve chamber being cut away andthe draftflue vFig. 3 is a transverse section ofthe seat, taken on the line 3-3,'of.Fig. 2. 1

Although I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be inderstood as being limited to the specific structure chosen for illustration, for various alterations and modifications may be made in the details of construction. and arrangement of parts,fwithout departing from -,the spirit 1 and scope of the invention as defined in the appended claims p Referring now, to the illustrations, 6, represents the usual closet-bowl.

In the present embodiment a seat forms walls of. the conduit.

ToILnr-vnN'rInAron-J the conduit andconsists of a tubular rim, ofany- 'suitable material and including an I, upper wall, 7, the edges of which are rounded; a bottom wall, 8, extending inwardly from the outer, lower edge of the top wall, and aflange, 9, depending from the inner edge ofjthe top wall. The flange extends a distance below the top plane of the bowl and is disposed in spaced relation to both the bowl and. the bottom wall of the seat, to afford apassage, 10, toadmit foul air and gases from the-bowl to the conduit.

The flange serves also to prevent splattering of water into the conduit. Thefront receives from the interior of the seat and has its rear end reduced as at 14, to enter a horizontal conduit 15, communicating with an upright draft-flue, or ventilating pipe, 16, preferably concealed within a partition wall, 17.

The conduit, 15, is formed with a vertical ofl'set, 18, which affords a convenient valvechamber. Within the offset portion, or valve-chamber, is asuitable valve, preferably comprising a disk, 19, having intles,

20, on its edges which penetrate the a jacent The valve extends normally horizontally across the valvechamber and thus closes the passage.

7 :Depending from the under sideof the valve, and from apoint coincident the pivotal axis thereof, is an arm, 21, which normally declines toward the front wall. of 100 the ofl'setportion and is engageable by a 1pTlunger-rod, 22, protruding throu h the out wall of the ofl'set portion and s idable in a bearing, 23,'thereon. The outer end of Specification of Letters rat'ent. Patented Nov. 20, 1917. i

the rod is provided'with a shoulder, 24, be

tween which and the bearing is interposed a compression spring, 25. c

The elbow, 13, is provided with an ear,

26,5 l engaging the outer end of the plungerro Y The pivotal axis of the valve is positioned between the front edge and the diametrical axis of-the disk, to increase the weight of a the valve in the rear of its pivot, whereby the valve will close by gravitation when released by the plunger-rod. I

The yieldable plunger-rod serves normally to hold the seat'slightly raised, as

shown in Fig. 1, and depression of the seat to the dotted osition shown, causes the elbow to enter the conduit 15, and coact with the plunger to open the valve, thus exposing the airpassage under the seatto the action of the draft to carry away the gases.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,

1. A ventilator for a water-closet having a bowl, including a tubular-rim comprising top of the bowl, and a flange depending 1 from the inner edge of the top wall a disa top and outer wall, a bottom wall secured to the outer wall and adapted to rest on the tance below the plane of the top of the'bowl and disposed in spaced relation to the bowl and the bottom wall; a v

2. A ventilator for a water-closet having a bowl, including a tubular rim comprising a top and outer wall, a bottom wall secured to the outer wall and adapted to rest on the top of the bowl, and a flange depending from the inner edge of the to wall a distance below the plane of the top of the bowl :1 bottom wall extending inwardly from the lower outer edge of the top wall and adapted to rest on the top ofthe bowl, and a flange depending from the top wall a distance below and disposed in inner edge of the spaced relation to the bottom wall, the front portion of the flange being extended downward relatively a greater distance than the b rear and side portlons.

In testimony whereof, I have hereunto set my hand this 25th day of September, 1916'.
